Account deletion is permanent and will remove data associated with your account, so you won't be able to make an account again in the future.
Account Deletion (One Method)
....through our help chat when logged into our website:
Select "Help" button in the bottom right.
Select "Send us a message."
Select "Account Deletion" and complete the workflow for account deletion.
Your request will be submitted to us and you'll receive a confirmation when the deletion has been completed. Please note that it may take up to 4 weeks for your request to be completed.
You must be logged into your OpenAI account (i.e. https://openai.com/login) for this process, as we must confirm that you are the account holder. Requests made without an associated account cannot be processed.
